Comparison of cell count on HeLa cells using fluorescence and transmitted light. unlabeled cells was consistent across wells that were not overly-confluent (Figure 4).įigure 2. A comparison of cells detected using stained nuclei vs.
Count adherent or suspension cellsĪdherent monolayers or suspended cells could be quantitated using one of the three transmitted light (TL) cell counting analyses protocols based on cell size or the Cell Count module for detecting fluorescently stained nuclei (Figures 2 and 3). The transmitted light images were acquired at a z offset of -40 µm using a 10x objective.

Comparison of different cell types from 156-20,000 cells/well shows CellReporterXpress software modules that segmented the transmitted light images most accurately. For cells like HepG2 which grow in clumps, accurate segmentation can be challenging at high densities, so it may be advisable to use the measurement “Area covered” instead of “Cell count” to get more accurate results.įigure 1 Figure 1. The corresponding TL modules yielded cell counts that most closely agreed with the quantitation achieved using a nuclear stain over the widest range of cell densities. In the experiments reported in Figure 1, however, cells were plated into 96 well plates from fully confluent to only a few cells per well. “Transmitted Light Cell Count, General” works well for most monolayer cell culture (CHO, Hela, PC-12) that is neither too confluent nor too sparse. Three modules are included in CellReporterXpress software for counting cells in transmitted light. Select the best transmitted light module for your cells On-the-fly analysis allows for simultaneous analysis of an image during acquisition. Fluorescent and transmitted light images were acquired consecutively (transmitted light first) and cells were counted using on-the-fly analysis. Plates were read on the ImageXpress Pico system with a 4x or 10x Plan Fluor objective, one field of view/well.
Count nuclei imagej serial#
In the following experiments, several cell types were plated into 96 well plates in 1:2 serial dilutions and grown overnight before being labeled with 5 µM Hoechst or DRAQ5 nuclear stain for 30-60 minutes inside an incubator at 37☌, 5% CO 2. In this application note, we demonstrate how the user’s choice of transmitted light segmentation (analysis) algorithms increase the accuracy of counting diverse cell types and compare the results to those found when using a nuclear stain. The ImageXpress ® Pico Automated Cell Imaging System with CellReporterXpress ™ Image Acquisition and Analysis Software is ideal for quantitating cells whether label-free or fluorescently stained. In both cases, the enumeration of the cells through software segmentation should be fast and reliable. These applications may make use of endpoint assays for imaging fluorescently stained nuclei or may demand robust transmitted light imaging of unstained live or fixed cells. The ability to accurately quantitate cell number in multi-well microplates enables a multitude of biological applications that study cell health or proliferation.
